Abstract: A humidity sensor for use in a medical breathing circuit. The sensor comprises a sensor (10) located in the medical breathing circuit and a source of infrared radiation (13, 14) and an infrared detector (35) which are located remote from the sensor (10). Infrared radiation of a selected frequency spectrum is generated by the source (13, 14), propagated through an optical fibre (17) to the sensor (10) where it is pursed through gases in the breathing circuit and the remaining radiation is returned to the detector (35) through an optical fibre (27). The radiation incident on the detector (35) is a measure of the humidity of the gases in the breathing circuit.

Abstract: An optical fiber moisture sensor includes an optical fiber coated with a thin film of plasma polymerized hexamethyldisiloxane and ammonia, 1-2 µm thick. The light transmission characteristics of such a coated optical fiber changes as a function of moisture conditions in an environment to which the coating is exposed. Accordingly, the coated optical fiber may be utilized for sensing changes in moisture conditions in an environment by being placed in the environment, causing light to be transmitted through the fiber and detecting changes in the light transmitted through the fiber as a function of the moisture conditions in the environment.
